The "includes weekday and relative time" test computed the expected
weekday with the ambient host locale (`toLocaleDateString(undefined, ...)`)
while `formatNextRun` formats the weekday through `i18n.getLocale()`
(default "en"). On hosts whose default locale is not English (e.g.
`LANG=zh_CN.UTF-8` -> "周一"), the two diverge and the slice assertion
fails: `expected 'Mon,' to be '周一, '`.
Mirror `i18n.getLocale()` in the test so the expected weekday always
matches the locale the presenter uses. No production behavior change.
Verified: passes under `LANG=zh_CN.UTF-8` and `LANG=C` via
`pnpm test:unit:fast -- test/ui.presenter-next-run.test.ts`.
AI-assisted.
Refactor the Control UI around route-owned page lifecycle and state while preserving existing behavior and design.
